Salamanders are generally agreed to represent the primitive tetrapod body plan, as well as a postural analog for early tetrapods. Dissection and description of the muscles of the forelimb, trunk, and hindlimb of the California newt, Taricha torosa, were undertaken to provide baseline data on the locomotor structures in this species. Hypaxial trunk muscles are similar to those of other vertebrates. As in other salamanders, limb muscles show a simple parallel-fibered architecture and often span multiple joints. Several differences in limb musculature were also noted. The extensor iliotibialis muscle possesses a single head in T. torosa, rather than the two heads common in larger salamander species. The ischioflexorius muscle, while divided into proximal and distal sections, is not distinct from the puboischiotibialis in its proximal portion. The femorofibularis is enlarged in this species; it is suggested that the femorofibularis and ischioflexorius muscles may be functionally analogous systems. Forelimb and hindlimb musculature show similar morphological patterns, particularly in distal limb segments, which may provide insight into the primitive arrangement of tetrapod limb muscles.
